What is Bluetooth wireless technology?  
HSP (Headset Profile)*2: Talking on the  
phone/Operating the phone.  
HFP (Hands-free Profile)*2: Talking on  
the phone/Operating the phone by  
hands-free.  
Bluetooth wireless technology is a  
®
short-range wireless technology that  
enables wireless data communication  
between digital devices, such as a  
computer or digital camera. Bluetooth  
wireless technology operates within a  
range of about 10 metres.

When you use a Bluetooth mobile phone  
supported by both HFP (Hands-free  
Profile) and HSP (Headset Profile), set to  
HFP.  
Connecting two devices as necessary is  
common, but some devices can be  
connected to multiple devices at the  
same time.  
You do not need to use a cable for  
connection, nor is it necessary for the  
devices to face one another, such is the  
case with infrared technology. For  
example, you can use such a device in  
a bag or pocket.  
Bluetooth standard is an international  
standard supported by thousands of  
companies all over the world, and  
employed by various companies  
worldwide.  
Notes  
To be able to use the Bluetooth function,  
the Bluetooth device to be connected  
requires the same profile as the unit’s.  
Note also that even if the same profile  
exists, devices may vary in function  
depending on their specifications.  
Due to the characteristic of Bluetooth  
wireless technology, the sound played on  
this unit is slightly delayed from the sound  
played on the Bluetooth device during  
talking on the telephone or listening to the  
music.  
Communication System and  
Compatible Bluetooth Profiles  
of this unit  
Profile is standardization of the  
function for each Bluetooth device  
specification. This unit supports the  
following Bluetooth version and  
profiles:  
Communication System :  
Bluetooth Specification version 2.1 + EDR*1  
Compatible Bluetooth Profiles:  
A2DP (Advanced Audio Distribution  
Profile): Transmitting or receiving audio  
content of high-quality.  
AVRCP (Audio Video Remote Control  
Profile): Controlling A/V equipment;  
pausing, stopping, starting playback,  
volume control, etc.

How to install the earbuds  
correctly  
1
Clip this unit to a pocket, etc.,  
of your clothes and then wear  
the headphones.  
If the earbuds do not fit your ears  
correctly, low-bass sound may not be  
heard. To enjoy better sound quality,

of the earbuds by checking the colour  
inside. When you change the earbuds,  
install them firmly on the headphones  
to prevent the earbud from detaching  
and remaining in your ear.  
Wear the earphone marked in  
your left ear, and the one marked  
in your right ear.  
Tip  
Move the cord slider to change the split  
position of the cord, to prevent the  
headphones coming apart when the unit  
is not in use.

ADDITIONAL INFORMATION  
Precautions  
Use this unit at least 10 m away from  
the wireless LAN device.  
On Bluetooth communication  
Bluetooth wireless technology operates  
within a range of about 10 metres.  
Maximum communication range may  
vary depending on obstacles (human body,  
metal, wall, etc.) or electromagnetic  
environment.  
The aerial is built into the unit as  
illustrated in the dotted line. The  
sensitivity of the Bluetooth communication  
will improve by turning the direction of  
the built-in aerial to the connected  
Bluetooth device.  
The communication distance shortens  
when the obstacles are between the aerial  
of the connected device and this unit.  
If this unit is used within 10 m of a  
wireless LAN device, turn off the  
wireless LAN device.  
Install this unit and Bluetooth device as  
near to each other as possible.  
Microwaves emitting from a Bluetooth  
device may affect the operation of  
electronic medical devices. Turn off this  
unit and other Bluetooth devices in the  
following locations, as it may cause an  
accident:

occur and resulting in communication  
speed deterioration, noise, or invalid  
connection if this unit is used near a  
wireless LAN device. In such as case,  
perform the following.  
Depending on the device to be connected,  
it may require some time to start
